Abstract

Abstract: Facing with the problem that the floor evacuation simulation only annotates the floor plan route, which is relatively single and not intuitive, a 3D building evacuation simulation method integrating mixed reality and building information model is proposed. The BIM components are reasonably planned and segmented, and reasonable annotation is performed. The BIM information is routed through the surface area heuristic optimization algorithm based on the bounding volume hierarchy. The evacuation simulation process is imported into the Microsoft Hololens2 hardware platform using the Unity3D development engine. The experimental results show that, compared with the previous evacuation simulation expressed only by the building plan, by introducing MR equipment as a source of multi-source perception providing device, the evacuation simulation is extended to the interactive real three-dimensional space, which can make the evacuation guidance process more intuitive, the simulation guidance efficiency is higher and the experience is stronger.
